Thank you for viewing this item. This canopy is an advanced L size. I've used it the most over my 40 years of flying, with approximately 60 uses. This canopy comes in S, M, and L sizes. I have both M and L sizes. You might think that a larger canopy would be slower, but the L size is actually faster than the M size, and the handling is more relaxed. A key feature is that it has never collapsed, even in turbulent conditions with strong thermals. Even when the previous pilot's canopy collapsed, this one didn't. The intake is large. We don't trust manufacturer data, so we speak from our own test results. I will also be selling an M size on Mercari later. This is a used item, so please refrain from purchasing if you are overly concerned about condition. Please understand that it is non-refundable and non-returnable. Payment can only be made through Mercari, but you are welcome to come and see it in person. The price of the canopy is difficult to determine, so please feel free to ask any questions. I don't check my email often, so if you don't hear back from me, please contact me by phone. Thank you. Takashi Ito, Chairman of Tokai Sky Club 09039685637
